Subject: [ECOS] RedBoot network timer question

Are the following observations correct?

 1) The network code keeps track of millisecond "ticks" by
    delaying for 1ms and incrementing a counter every time any
    of the code uses the MS_TICKS() to check the current time.

 2) But, the network polling code is only called once every
    250ms [the timeout value passed to gets() by the main
    loop].  I verified this by pinging the board and response
    times varied from 4m to 290ms with a mean of 144ms.

 3) That means that the network time only increments by a few
    milliseconds once every 250ms.  Time would appear to pass
    very slowly to the network routines, making the TCP
    timeouts longer by a factor of about 100.
